Chareyre proposed the following answer:
Hi,

The law you are using is perfectly elastic-plastic. It has no viscosity.
If you want viscosity at contact you have other laws like
Law2_ScGeom_ViscElPhys_Basic.
However, if you have problems with unstable facet-spheres interactions,
viscosity at contact will probably not help.
We know that a few problems remain in facet-sphere interactions. If you
can exhibit the instability in a simple script, please open a bug and
attach the script. It will help us to solve the problems.

Yes, maximum Newton's damping is 1.
